Twelve role-shaped helpers cover a solo founder's whole week out of the box.
Sintra hands a solo founder twelve named helpers in a web app, each good at drafting its own slice of the week. Beagle is one teammate inside the channel where your team already talks - it reads the thread, does the work across your tools, and waits for your nod.
Sintra is an AI employee platform. A subscription web app with twelve role-based AI helpers for small-business work like posts, emails and SEO. Here is where the two part ways.
| Sintra | Beagle | |
|---|---|---|
| Where it lives | Its own web app, plus iOS and Android. | Slack and Microsoft Teams, as a teammate. |
| Reads your channels | No - you brief each helper yourself. | Every channel it is invited to, scoped to what each teammate can see. |
| Takes initiative | You open a helper and ask. | Pipes up unprompted when something needs you. |
| Acts across your tools | 40+ listed integrations, with drafts as the main output. | Drafts and does the work across ~2,700 connected apps. |
| Learns your team | Brain AI holds your brand voice and files. | Remembers your tone, your people and what you decided. |
| Asks before acting | You are the send button. | Always waits for your nod before anything goes out. |
| Pricing | Flat subscription, not per seat, with 250 credits a month. | Free to start - 1,000 credits, no card. $49/mo adds 5,000 monthly. |

The shape of work Sintra was not built for.
Beagle is a teammate in Slack and Microsoft Teams, not a tab you switch to. It reads the channels it is invited to and answers in the thread.
It drafts the reply, updates the record and chases the action item across ~2,700 tools - then waits for your nod before anything goes out.
Correct it once and it remembers. Over time it knows your tone, your accounts and your decisions - the part Sintra leaves to you.
